が低下するという欠点がある。[0003] PPE resins are relatively inexpensive, have excellent mechanical properties, electrical properties, heat resistance, etc., and have good dimensional stability. Therefore, it is used in many applications as engineering plastics. However, since this resin has the drawback of being inferior in moldability, impact strength and chemical resistance, a resin blended with an aromatic vinyl resin such as polystyrene is usually used. However, this blend has a drawback that heat resistance and flame retardancy are lowered.

There is a demand for a resin composition that makes use of the excellent characteristics of PE-based resins and compensates for the defects. However, conventionally, in a blend of thermoplastic resins having different properties, different polymers are usually poor in compatibility and therefore not uniformly mixed, and so-called "sea-
The "island" structure is formed, and this "sea-island" interface is extremely weak, so that the resulting composition is fragile, and mechanical strength and impact strength are deteriorated. Blends of the above polyetherimide-based resins with PPE-based resins are described in US Pat. No. 4,431,779 to White et al. Such blends are of interest because the components are generally compatible and the mixture has good impact strength in addition to good mechanical properties. However, these blends typically undergo phase separation and delamination due to the presence of large, incompletely dispersed PPE particles in them and the lack of interphase interactions between these two resins. is there.

また、射出成形品の破断面の走査型電子顕微鏡（ＳＥ
Ｍ）（５０００倍）写真を図８および図９に示す。[Table 1] In Examples 1 to 3 to which the styrene-glycidyl methacrylate copolymer as the compatibilizer was added, the heat resistance was slightly reduced as compared with Comparative Example 1 in which no compatibilizer was added, but the compatibility was obviously improved. I understand. From FIGS. 1 to 3, looking at the morphology of the resin composition, in Examples 1 to 3, the dispersed particle size was small, and the adhesion at the interface between both resins was good. Comparative Example 2 in which polystyrene was added instead of the styrene-glycidyl methacrylate copolymer (Fig. 7)
In comparison with Example 3 (Fig. 6), the dispersed particle size is obviously larger and the adhesion at the interface is not good. Moreover, it can be seen that the surface appearance is also poor. Example 4 and Comparative Example 3 Pellets were produced and molded in the same manner as in Examples 1 to 3 except that the respective components were mixed in the proportions (parts by weight) shown in Table 2. Using the obtained test piece, Izod impact strength (A
STM D256), tensile strength (ASTM D63
8), elongation at break (ASTM D638) and heat distortion temperature (ASTM D648) were measured. Further, the surface appearance of the molded product was visually evaluated. The results are shown in Table 2.
In addition, a scanning electron microscope (SE
M) (5000 times) photographs are shown in FIGS. 8 and 9.
